Associations of Combined Moderate and Vigorous Physical Activity With All-Cause, Cardiovascular, and Cancer Mortality: A Cohort Study of 586 936 US Adults.
Article in Journal of the American Heart Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAlthough both moderate-intensity physical activity (MPA) and vigorous-intensity physical activity (VPA) are recommended, the optimal combination of intensities for maximal health benefits remains uncertain. This study examined the associations of MPA, VPA, and combined moderate-to-vigorous physical activity (MVPA) with all-cause, cardiovascular disease, and cancer mortality.
methodsWe analyzed data from 586 936 adults, aged ≥18 years, in the US National Health Interview Survey (1997-2018), linked to mortality through 2019. Participants were categorized as inactive, MPA only, VPA only, or MVPA. Among those engaging in MVPA, we further classified participants by activity frequency and the proportion of VPA. Cox proportional hazards models estimated hazard ratios (HRs) and 95% CIs for all-cause, cardiovascular disease, and cancer mortality, adjusting for sociodemographic, lifestyle, and clinical factors. Sensitivity analyses excluded individuals with baseline chronic diseases or deaths within the first 2 years.
resultsOver a median 10.0-year follow-up, 82 959 deaths occurred. Compared with inactivity, MPA only (HR, 0.74 [95% CI, 0.72-0.76]), VPA only (HR, 0.56 [95% CI, 0.54-0.59]), and MVPA (HR, 0.50 [95% CI, 0.48-0.52]) were associated with progressively lower all-cause mortality. Similar patterns were observed for cardiovascular disease and cancer mortality. Across all MVPA volumes, individuals with >25% of MVPA from VPA had the lowest mortality risks. Findings were consistent across subgroups and sensitivity analyses.
conclusionsVPA was associated with greater mortality reduction than MPA, and combining both intensities conferred the strongest survival benefits. These results support current guidelines and highlight the importance of incorporating VPA, when feasible, into public health strategies.
